Hacking [Question] Restoring other's NAND.bin to your own 3ds

[TheDuckMan64]

So after reading the wiki (
http://wiki.gbatemp.net/wiki/3DS_Flashcart_FAQ#Can_I_restore_another_3DS.27s_NAND_backup.3F), there is no explanation. Why can a brand new 3ds that has been hardmodded straight out of the box not restore someone else's NAND.bin onto itself?

 

[Mrrraou]

Because the NANDs encryption keys are 3DS unique.
Flashing other's NAND to your own 3DS would brick it.

Because NANDs are unique for every system, think of it like having an individual fingerprint that can not be changed to match yours.

But why can a 3ds with no "NAND" (aka a brand new one that hasn't been turned on (it literally no NAND, ) not "adopt" the other NAND? Or does it have to do with a key that is unique to that 3ds, no matter how many times you reset it?

EDIT: Not sure how to word this question very well. Of course the new 3ds has a NAND, it's just... un-setup?

A 3DS always have a NAND. When it's never turned on, it still has its own NAND, the configuration and user data are just reset.

Are there also configs that do not get setup when we first setup the 3ds? Ones that are made when the 3ds is put together?

It's part of the hardware. You could do a motherboard swap if you wanted to.

For the most part, it's set up in the factory as part of the manufacturing process, it's only a few user settings that are left to be configured by the user.

So if we, for example, did a more complicated hard mod and extracted the NAND.bin and the other encryption keys and whatnot (if they are accessible), we could then put them on a different 3ds and it should work?

EDIT: But we would have to deal with the issue of online stuff...

No. Swapping motherboards would be easier (and possible).

I'm not asking what easier, I was just wondering if it would work/ is it possible?

The encryption keys are stored in a chip. It would *maybe* work, but you would have to clone that chip, and, well... That would be extremely hard, costly, and you would break the other N3DS. So that's useless and a big waste.

 

[Just3DS]

Off topic but I always wondered. How they configure/write chip-specific NAND in factory? Of course one has to first know the unique key of the SoC and then input it somewhere in a stock NAND to make it work... there must be a factory hardware machine or a computer software that does this... (in which case if it got leaked we can make our own sysNAND CFW)

Also have this doubt , wanted to do the test, I have a N3DS brincked want to try to put the Nand another N3DS using hardmod and win32 . I guess that the serial may have some importance in it. My serial begin with QW4017.

As already stated, it won't work.
